Grounding
•
Pump: Order Grounding Wire and Clamp Kit,
Part No. 222011. See Grounding the Pump and
F
•
Hydraulic Hoses and Fluid Outlet Hoses:
Use electrically conductive hoses only.
•
Hydraulic Power Supply: Follow manufac-
turer’s recommendations.
•
Flushing Pails: When flushing, only use metal,
grounded pails. Make firm, metal-to-metal con-
tact between the metal part of the dispense
valve and the pail. Use lowest possible pres-
sure.
Grounding the Pump
To ground pump (See F
. 1):
1.
Remove ground screw (Z) and insert through eye of
ring terminal at end of ground wire.
2.
Fasten ground screw back onto pump and tighten
securely.
3.
Connect other end of wire to a true earth ground.
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
The system pressure must be manually relieved to pre-
vent the system from starting or dispensing accidentally.
For the following instructions, see F
IG
. 2.
1.
Shut off hydraulic power supply.
2.
Close supply line shut-off valve (L).
3.
Open dispensing valve to relieve pressure.
4.
Open pump outlet drain valve. Have a container
ready to catch drainage.
5.
Close return line shut-off valve (H).
6.
If you suspect the nozzle or hose is completely
clogged or that pressure has not been fully relieved
after following steps 1-5 above, very slowly loosen
the hose end coupling to relieve pressure, then clear
obstruction.
NOTE: Keep drain valve open until you are ready to dis-
pense again.
The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes
to ignite or explode. Grounding provides an escape
wire for the electric current.

This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief
Procedure when you stop spraying and before
cleaning, checking, or servicing the equipment.
